Last night, Cartier threw a star-studded party at Shoreditch Town Hall to celebrate Magnitude, the Maison’s new High Jewellery Collection. After dinner, guests including Claire Foy, Ella Balinska, Letitia Wright and Iris Law were treated to an electric performance from Beth Ditto, before heading downstairs to dance the night away to sets by DJs Paul Sevigny and Mimi Xu.

One special guest, Lily Collins, invited Vogue over to get ready with her before the gala. So what does the actor listen to to get her in the mood while she's preparing for a red-carpet event? "My music choices tend to be all over the place when I’m getting ready," Collins revealed. "It really depends on our vibe for the night. It can go anywhere from Kygo, Khalid, and Katy Perry dance tracks, to retro disco hits, classic Motown tunes, or epic '90s throwbacks. I usually let Spotify guide my mood."

For the cocktail attire dress code, Collins chose a plunging embellished black suit to best show off the breathtaking yellow diamond, sapphire and lapis lazuli Cartier necklace that completed her outfit. "The moment I saw this stunning necklace I knew it was the one. The combination of the blue sapphires and yellow diamonds were so captivating and the exquisite neckline of the piece stood out. I knew I wanted it to stand alone on my skin so we were sure to find an outfit that allowed the necklace to breathe on its own and have the moment it deserves. Similarly, as far as beauty, we wanted to complement its colours and geometric design so we let those inspire us."

One of the first out of her seat as soon as Beth Ditto took the stage, Collins is certainly fond of a little dance. "To be honest, it doesn’t take that much to convince me to get up. But of course if a female anthem comes on from Spice Girls, Robyn, Rihanna, or Jess Glynn I’d jump straight on it even faster. I’d also never turn down “Ain’t Too Proud To Beg” by The Temptations. Motown hits are the best!"
